This is an analysis of how accessible the Toronto Transit Commission is in serving the city and the effectiveness of the distribution of accessibility. 

An initial analysis of the commute behaviour of the residents of Toronto based on data provided by the Transit Tomorrow Survey, to understand the way in which residents of Toronto either use or do not use public transportation, looking primarily at the locations of the commuter destinations with respect to the other destinations and developed transportation networks within the city. The data from the survey was sorted tot he top 20 destinations for both vehicular and public transit commuters in order to better understand these patterns. 

A colour gradient (point density) over the city was generated based on the density of points of origin of these commuters to understand where commuters for transit and car were coming from. Point densities was also used to produce another gradient representing the density of transit stops within the city. To test the accessibility and effectiveness of TTC distribution, the commuter origin density was overlaid to identify zones in the city where: 

1. Transit commuters using public transit where it was not accessible 

2. Driving commuters where public transit is highly accessible


This study found gaps in accessible transit around the fringe of the city and near the water front. The downtown core and residential neighbourhoods adjacent to downtown on the other hand had many driving commuters even though public transit was highly accessible. An analysis of the demographics of these zones helped to explain some of these results. For example. the wealth in the residential neighbourhoods adjacent to downtown explained the greater use of private vehicles. Furthermore the demographics analysis also indicated that of zones without adequate TTC access, three zones were particularly critically needed better TTC access due to income and density circumstances.
